Gerhard Ertl Lecture & Award

Gerhard Ertl Lecture & Award

The Ertl Lecture Award was established in 2008 by the three Berlin universities (Humboldt University, Technical University and Free University) and the Fritz Haber Institute of the Max Planck Society and is awarded once a year. It commemorates former FHI Director Gerhard Ertl's Nobel Prize in Chemistry, which he received in 2007. The prize honours outstanding personalities and researchers in the field of catalysis where Ertl carried out exceptional research for many decades. The prize, sponsored by BASF, includes a one-week research stay at the participating Berlin institutions and a keynote lecture. The winner is typically announced in Spring, the lecture takes place around the December 10th, the anniversary of Ertl's Nobel Prize reception.

Charge-carrier dynamics and optoelectronic properties of metal halide perovskites for solar cells

  • Online Seminar

Over the past decade, metal halide perovskites have become renowned for their rapidly improving performance as photovoltaic active layers. This success has however often outpaced understanding of the electronic processes occurring within these materials. In this talk, I will give an overview of my work on the factors influencing electron motion and recombination in a series of metal halide perovskites, ranging from the archetypal CH3NH3PbI3 to the double-perovskite Cs2AgBiBr6. Using a combination of optical spectroscopy with computational techniques, I have investigated electron-phonon coupling [1], trap-mediated recombination [2], halide segregation [3] and intrinsic quantum confinement [4] within these materials, developing quantitative models to explain these phenomena.
